    Monitoring Your Medium Voltage Switchgear

    When I worked in the offshore oil & gas business many years ago, production platforms typically had low-voltage electrical systems running motors no larger than 480VAC. Over the years as the process sophistication grew and motors with variable speed drives replaced engine-driven compressors and other assets, the need for medium voltage systems (between 1KV and 35KV) grew. For most other industries with access to an...

    Reliable Electrical Power and Utilities at the University of Texas

    As a University of Texas electrical engineering graduate, it is great to hear a success story on the successful electrical load control using Emerson technology on the main campus in Austin, Texas. The campus operates an independent electrical grid but connects back to the Texas electrical grid. The utilities department has a $2.8 million operating budget. The utilities group produces 140MW of electrical power and provides...

    Simulator Helps Drive Cultural Change Toward Operational Excellence

    At the 2017 Ovation Users Group conference, there was a presentation by an electrical power producer on driving cultural change and operational excellence through the use of simulation in the Ovation distributed control system . The facility had a 92% capacity factor so it was basically running all the time. The facility was challenged with aging workers and losing valuable experience. They decided to commit to a formal...

    Comprehensive Cybersecurity for Critical Infrastructure

    The electrical power generation and distribution industries, especially here in the U.S., have a long history in working to improve reliability and security. This history goes back to the establishment of the North American Electric Reliability Council (NERC) in the late 1960s as a response to a widespread blackout in the Northeastern U.S. NERC became the North American Electric Reliability Corporation (also NERC)...

    Continuously Monitoring Critical Electrical Assets

    One common thread with Industrial Internet of Things (IIoT)-based sensors is that they typically will replace periodic, manual measurements. We shared IIoT application examples in past posts of how business performance—in safety, reliability and efficiency—can be improved. The common thread is that continuous data streams from these IIoT sensors feed analytics applications, which can help spot & notify personnel of...

    Avoiding Dangerous Malware Infections

    The malware WannaCry/WannaCrypt has been all over the news recently. Since most of the operator and engineering workstations used in distributed control systems (DCSs) and supervisory control and data acquisition systems (SCADA) are PC-based, the question was naturally could these have been/or be impacted by this dangerous malware. I caught up with Emerson’s Jaime Foose . She noted that it is important to point...

    Improving Burner Control with Gas Chromatographs

    There once was a time for industrial manufacturers when they received fairly homogeneous supplies of natural gas that did not vary much in energy content. Here in the U.S. with the rapid increase in shale gas production as part of the overall energy mix, there is more variance. In a Power magazine article, Gas Chromatographs Offer New Technology for Power Plant Burner Control , Emerson’s Bonnie Crossland describes...

    Improving Power Plant Staff Effectiveness

    Author: Douglas Morris With the large number of power workers having already retired, there is a definite shortage of expertise within the industry. Not only are workers new, but companies are having difficulty hiring enough skilled employees. Although most new hires are diligent and eager to learn, they lack the experience necessary to make critical decisions. Younger engineers, technicians, and operators may have...

    Improving Flexible Power Plant Operations

    Author: Douglas Morris Increasingly, plants are having to adapt to more flexible operations as gas prices remain low and renewables are added to the generation mix. Gas units are shut down, started up in the morning, follow load during the day, and then are shut down or idled again. Source: National Renewable Energy Laboratory: The Western Wind and Solar Integration Study Phase 2 Coal plants are also asked to operate...

    Increasing Power Plant Reliability via Smart Monitoring and Diagnostic Centers

    Author: Douglas Morris Today’s fossil power plants are faced with the challenge of stabilizing the fluctuating grid power supply due to renewable generation and, as a result, plants originally designed for base load are subject to load cycling. A principal consequence that cycling imposes is increased amounts of thermal stress ( creep fatigue ) on boilers and heat recovery steam generators (HRSGs) which contributes...
